I agree that the nextion UI looks better, but there's no fundamental reason the v6 screen can't look better than it currently does (if not identical to the nextion), especially if the drawing routines can be sped up.
The nextion displays look good because:
1) people have invested time in making them look good
2) the screens have a dedicated microprocessor to render the UI
3) The current v6 drawing routines are MVP (minimum viable product) - they are literally just bordered rectangles at this point
I suspect there will be improvements to the stock v6 UI in the upcoming months, but it will likely never perform or look as good as the nextion, due to the computational cost.
